Shown for all children (n = 10,622; 24 missing values) and separately for girls (n = 5,579; 15 missing values) and boys (n = 5,043; 9 missing values).
In the WHtR >0.5 group, no individuals fell into the thinness category.
Comparison between sexes, results from Pearson's χ2 test.
Specificity (percentage in bold): the number of children with thinness or a normal weight and a WHtR ≤0.5 divided by the total number of children with a WHtR ≤0.5.
Sensitivity (percentage in bold): the number of children with overweight or obesity and WHtR >0.5 divided by the total number of children with a WHtR >0.5.
